Abstract (en)

[origin: EP1724261A1] Long-lived charge separation is attained with high efficiency by using a supramolecular complex utilizing pi-pi interaction. A supramolecular complex is formed by pi-pi interaction between extended viologen, the extended viologen having heteroaryls coupled together by a linking group with pi-electron conjugated system, and porphyrin. As a result of study of photoelectron transfer reaction, it has been found that within the supramolecular complex, efficient electron transfer occurs from the singlet excited state of porphyrin to the extended viologen, thereby obtaining a charge separation condition of extremely long lifetime exceeding 1 millisecond.
